Abstract:Photonic integrated components with tunability, low power consumption and low fabrication cost are of considerable interest for optical communications and optical signal processing systems. Based on the high thermo-optic coefficient of polymer material, we demonstrate a tunable integrated waveguide ring filter with a novel but very simple UV-based soft imprint technique. By properly incorporating a Mach-Zencher interferometer (MZI), the tunability of the ring filter's coupling states and resonant wavelength are realized flexibly by the micro-heaters. The tuning efficiency of resonant wavelength is 8.2 pm/mW within one free spectrum range of the ring filter. (C) 2013 Elsevier B.V. All rights reserved.
